CLAUD E. FULLER, 0F NEW YORK, N. Y.

Application led December 20, 1922. Serial Nb. 603,058.

ToY all whom it may concern."

Be it known that I, CLAUD E. FULLER, a citizen of the United States, and a resident of New York, in the county and State of New York, have'invented an Improvement in Conveyers, of which the following descri tion, in connection with the accompanying rawings, is a specification, like letters on the drawings representing like parts.

My present invention relates to conveyers, and more particularly to a dead roll conveyer adapted for use in a brick hacking machine. p

In mechanical handling otbrick itis desirable that a dead roll conveyer or antifriction table be positioned at. the end of a storage conveyer and in front of a backing apparatus. Such storage conve erA is described and claimed in my copen ing application, Serial No. 608,057, filed Dec. 22, 1922 and my present invention is adapted to be associated therewith.

1n my present invention the pallets engage with the conveyer chains to move the chains and the preceding pallets step by step in a' forward direction from the loading to the delivery end thereof. ln carrying out my invention 1 provide a plurality of. anti-friotion rollers on which the sliding pallets are adapted to rollor slide, such anti-frictionl rollers maintaining the pallets out of engagement with the surface or runs of the conveyer chains and in which the pallets engage with spaced rojections on the conveyer chains to positively move such chains in a forward direction, the speed and distance of each step in the onward travel of the conveyer dependin on the speed with which the pallets are elivered to the conveyer and with the width of the pallets., My improved device also properly spaces the pallets and means are a so provided for preventing undue endwise movements of the pallets with respect to each other, thus resulting in a devlce that pro erly positions a predetermined number o parallelly arranged pallets in alinement with the pushing device.

1n the accompanying drawings illustratiing a prefered embodiment of my invention, Fig. 1 is a lan view; Fig. 2 is a slde elevation; Fig. 3 is a sectional end elevation on the line 3-3 ot Fig. -1, and

Fig. 4: is a detail ot a section of the conveyer chain.

VReferring tothe drawings, 10 designates side frames, one end of'which, the left hand end, forms an angle awith the main ortion and the side members 10 are space apart and tied together by cross members 11 and sway braces 12. Secured to theoutside of each of the side plates 10., is an angle iron member 13 which extends lengthwise of eachl of the side members 10, the outer face o onel of the arms of such angle iron member 13 lying in a horizontal plane below the horizontal plane passing through the upper edge of the side plates 10. rlhis angle iron member 13 on each side plate 10 is secured to such side members 10 by a plurality of `spaced bolts 14 provided with a shoulder 15 that en'- gages the inner surface of the side members 10, and surrounding' the bolts 14 are bushings 16 which are used to maintain the angle iron with the upper outer surface of one arm thereof in a Ihorizontal plane, as clearly shown in Fig. 3. Secured to the an le iron members 13 and side plates 10 are p ates 17 which lie parallel with the side plates 10 with the upper edge thereof in substantially the same horizontal plane as lies the upper edge of the sideplates 10, a nut 18 securin the lates 17, angle iron members 13, an bushing 16 in position on the side members 10, providing thus a hollow trough 19 for a purpose to be hereinafter described'. The ends of both the angle iron members 13 'lie at an angle-with the main body of the same, forming in this manner an inclined run at each end of the plates 17. Secured tothe lett hand end of each side plate 10 by bolts 20 are downwardly extending brackets 21 vnear the lower end of each of which is pro- 28, thelsprocket wheels 28 beingy equal in pitch to the sprockets 23, and over the sprockets 23 and 28 run enless'sprocket conveyer chains 29, the upper reach ot these sprocket chains 29 runnin in the trough 19 andthe shape ot the sie plates 17 and angle irons 13 make -these sprocket chains "29' incline upwardly.' trom the. sprocket chains 23 then substantially parallel to the mit . and assuming, also, that loaded titl horizontal portion of the side plates 10 and then incline downwardly onto the sprocket 28, the travel of the sprocket chains being indicated by the arrow shown in Fig. 2.

The upper reach of the sprocket `chains 29 lies in a horizontal plane above, but substantially parallel to, the horizontal plane in which lies the upper edges of the plates 10 and 17.

The bolts 14 extend inwardly, with respect to the side plates 10, and on the inward extension is rotatably mounted antifriction rollers 30 such rollersY being secured to the inward extension of the bolts 14C by nuts 3l and the uppermost portions of each of the anti-friction rollers 3() lie in ahorizontal plane that is slightly above, but par-` allel to, thehorizontal plane in which lies the upper surface of the conveyer chains 29, as clearly shown in Fig. 3, this construction enabling the pallets 32, each carrying a plurality of brick 33, to roll over the antifriction rollers 30 and out of engagement with the conveyer chains 29. Each pallet 32, near the ends and on each edge' thereof, is provided with a cut-out portion 3d which, when there are a plurality of pallets on the conveyor, are in alinement with each other -on each side. At predetermined points along the length of theV conveyer chains 29, the distance between these points being de-f terniined by the width of the pallets 32, arel provided pins 35 which are adapted-to eX- tend upwardly above the pallets 32, and the distance between the chains 29 is such that the pins 35 will come into registry with the cut-out portions 34 so that, Vas the pallets` 32 move to the right, as shown in Fig. l, the forward cut-out portions-34 of the pallets 32 will engage with the pins 35 on the chains 29 and move the chains forwardly, the chains being adapted to be driven step by step in this manner.

Assuming the device to be constructed and assembled in the manner above described, pallets 32, each loaded with a plurality et bricks 33, are delivered onto the conveyer from the lett, such pallets will, in their onward movement,

engage with, tor example, the tirst pair oit upstanding pins 35, the upper ends or' which extend above the plane in which lies the top portions of the anti-friction rollers 3d, and assuming that a succession of such loaded pallets 32 is being delivered at the end of the machine, the next succeeding pallet will push the first pallet to the right, as viewed in Fig. 1, and the first pallet will, therefore, move the upper reach of the chains 29 to the right because or its engagement with the pins 35 and the next pair of instaan pins, riding up on the upwardly inclined portion of the runway 19, will move upwardly into the space between the alined cut-,out portions34 and this sequence of operations may be continued indefinitely, the conveyer chains 29 being moved forward step by step as the pallets 32 are delivered, the cut-out portions forming a substantially oval opening through which the pins 35 protrude, this pin cooperating with the cutout portions 34 to not only form a means for forcing the conveyer chains 29 forwardly in unison with the pallets 32, but also preventing undue endwise movement of the pallets withV respect to such conveyor chains.

While I have necessarily shown and described the preferred embodimentof my invention somewhat in detail, it is to be understood that I may vary the details of the construction and arrangement of parts within Wide limits without departing from the spirit of the invention.

Having thus described my invention, what l claim as new is:

. 1. In an improved conveyor, the combination of a pair of spaced frame members, a plurality of anti-friction rollers on each side of the frame and the anti-friction rollers on each side being in alinement with each other, a trough secured to the outer side of each of the frame members, an idler endless conveyer chain mounted for sliding movement in said trough and having the upper surface of the idler chain below the up er portions of the anti-friction rollersyarticle carrier means adapted to roll on said antifriction rollers and out of engagement. with the idler conveyer chains, and means on said idler conveyor chains adapted to be engaged by the article carrier means to move the idler endless conveyer chains forward step by step.

2.' An improved conveyor including a ramemember, a plurality of anti-friction rollers mounted on Ithe inner face thereof and with their upper edges in alinement and lying in a horizontal plane, a trough secured to the outer side, and extending lengthwise, thereof, .an upwardly inclined extension to said trough at the entrance end of the conveyer, a downwardly extending extension to said trough at the delivery end thereof, and an idler endless conveyor having the upper reach thereof slidable in said trough, and means on said idler endless conveyor adapted to engage with, and be driven by, an article to be moved. l

In testimony whereof, I have signed my name to this specication.l
